RED REEF GLAZE DISCLAIMER: This fantastic TSR glaze combination is our most volatile as the range of color is very wide. From mauve to oxblood red and some occasional seafoam green, this versatile glaze has hand-made drama. The red will not work on vertical surfaces as it will run and wash out. It works best inside of bowls and on flat surfaces. If color consistency is necessary you may want to reconsider. If variation is preferred this is your color.
